Use ImgeView with SpeakOut label and content instead of loading post URL for Posts

[kpchandora]

Currently while viewing a post, we are using the post URL and loading it using Glide.
The post URL is generated during the post creation. We take the ImageView canvas and convert it to bitmap then upload it to Firebase Storage.

Problem:

For different device screens, it will look different.

Solution:

Use ImageView background and display content on top of it.
